Aborted requests are the ones that were disrupted with http.ErrAbortHandler. For example, the timeout handler will panic with http.ErrAbortHandler when a response to the client has been already sent and the timeout elapsed. Additionally, a new metric requestAbortsTotal was defined to count aborted requests. The new metric allows for aggregation for each group, version, verb, resource, subresource and scope.
